Exploring Differences Among Video Gamers With and Without Depression: Contrasting Emotion Regulation and Mindfulness

Emotional regulation in Gaming Disorder: A systematic review

BACKGROUND AND OBJECTIVES

Problematic video game use is a source of concern. In addictions, difficulties with emotional regulation have become an important variable of interest. However, their study in relation to problematic video game use remains insufficient.

METHODS

A systematic review was conducted following PRISMA 2020 guidelines; 322 studies were screened, resulting in a final sample of k = 18 studies. The methodological quality of these studies was rated as moderate according to the McMaster Critical Review Form for Quantitative studies (CRF-Q).

RESULTS

There is evidence of relationship between different facets of emotional regulation and the presence of problematic video game use. Particularly, video games serve as escape strategy for suppressing emotional expression. There is no consensus regarding the nature of the relationship between emotional regulation, psychopathology, and problematic video game use, with various proposals suggesting moderation and mediation. There is also no consensus regarding the mediation of gender in the relationship between emotional dysregulation and problematic video game use. The level of certainty regarding the validity of the results was moderate.

DISCUSSION AND CONCLUSIONS

Emotional dysregulation plays a role in problematic video game use, especially through strategies as emotional suppression, and lack of abilities to understand and control emotions. It is important to consider emotional regulation as a potential target for research and intervention in clinical populations.

SCIENTIFIC SIGNIFICANCE

We review the largest sample of papers on problem gaming and emotion regulation to date. Our results highlight the importance of emotion regulation and, specially, emotional suppression, or negative escapism, on problematic video game use.

Emotional dysregulation in relation to substance use and behavioral addictions: Findings from five separate meta-analyses

Background/objective

Emotional dysregulation (ED) is a transdiagnostic variable underlying various psychiatric disorders, including addictive behaviors (ABs). This meta-analysis examines the relationship between ED and ABs (alcohol, tobacco, cannabis, gambling, and gaming), and indicators of AB engagement (frequency, quantity/time of use, severity, and problems).

Method

Searches were conducted in PubMed, Scopus, WoS, and PsycINFO. Five separate meta-analysis were run using random-effects models. Moderators (age, sex, continental region, and sample type; community vs. clinical), and publication bias were evaluated.

Results

A total of 189 studies (N = 78,733; 51.29 % women) were identified. ED was significantly related to all ABs. Problems and severity indicators exhibited the largest effects (r's .118-.372, all p <.023). There were larger effect sizes for cannabis problems (r = .372), cannabis severity (r = .280), gaming severity (r = .280), gambling severity (r = .245), gambling problems (r = .131), alcohol problems (r = .237), alcohol severity (r = .204), and severity of nicotine dependence (r = .118). Lack of impulse control exhibited some of the largest effects in relation to ABs. Clinical samples of cannabis users vs. community-based exhibited larger magnitude of associations.

Conclusions

Interventions targeting ABs should address lack of strategies and impulsive behaviors as an emotion regulation strategy specifically, as it is a common risk factor for ABs.

Depression and Internet Gaming Disorder among Chinese Adolescents: A Longitudinal Moderated Mediation Model

Internet gaming disorder (IGD) is significantly associated with depression across previous studies, and significantly affects the development of mental health among Chinese adolescents. In this two-wave longitudinal research, we tested the mediating role of maladaptive cognition and the moderating role of mindfulness in the linkage between depression and IGD among Chinese adolescents (N = 580, 355 females, average age = 15.76 years, SD = 1.31) who completed questionnaires. Results of regression-based analyses showed that depression was positively related to IGD. Maladaptive cognition significantly mediated the link between depression and IGD. Moreover, mindfulness moderated the second part of the mediation process. Specifically, as the level of mindfulness increased, the influence of depression on the future IGD through maladaptive cognition was weakened. The present study demonstrates the key roles of maladaptive cognition and mindfulness in the link between depression and IGD, and further supports the cognitive-behavioral model of pathological Internet use.

Subgroups of internet gaming disorder based on addiction-related resting-state functional connectivity

AIMS

To identify subgroups of people with internet gaming disorder (IGD) based on addiction-related resting-state functional connectivity and how these subgroups show different clinical correlates and responses to treatment.

DESIGN

Secondary analysis of two functional magnetic resonance imaging (fMRI) data sets.

SETTING

Zhejiang province and Beijing, China.

PARTICIPANTS

One hundred and sixty-nine IGD and 147 control subjects.

MEASUREMENTS

k-Means algorithmic and support-vector machine-learning approaches were used to identify subgroups of IGD subjects. These groups were examined with respect to assessments of craving, behavioral activation and inhibition, emotional regulation, cue-reactivity and guessing-related measures.

FINDINGS

Two groups of subjects with IGD were identified and defined by distinct patterns of connectivity in brain networks previously implicated in addictions: subgroup 1 ('craving-related subgroup') and subgroup 2 ('mixed psychological subgroup'). Clustering IGD on this basis enabled the development of diagnostic classifiers with high sensitivity and specificity for IGD subgroups in 10-fold validation (n = 218) and out-of-sample replication (n = 98) data sets. Subgroup 1 is characterized by high craving scores, cue-reactivity during fMRI and responsiveness to a craving behavioral intervention therapy. Subgroup 2 is characterized by high craving, behavioral inhibition and activations scores, non-adaptive emotion-regulation strategies and guessing-task fMRI measures. Subgroups 1 and 2 showed largely opposite functional-connectivity patterns in overlapping networks.

CONCLUSIONS

There appear to be two subgroups of people with internet gaming disorder, each associated with differing patterns of brain functional connectivity and distinct clinical symptom profiles and gender compositions.

Neural activations to loss anticipation mediates the association between difficulties in emotion regulation and screen media activities among early adolescent youth: A moderating role for depression

BACKGROUND

Screen media activities (SMAs; e.g., watching videos, playing videogames) have become increasingly prevalent among youth as ways to alleviate or escape from negative emotional states. However, neural mechanisms underlying these processes in youth are incompletely understood.

METHOD

Seventy-nine youth aged 11-15 years completed a monetary incentive delay task during fMRI scanning. Neural correlates of reward/loss processing and their associations with SMAs were explored. Next, brain activations during reward/loss processing in regions implicated in the processing of emotions were examined as potential mediating factors between difficulties in emotion regulation (DER) and engagement in SMAs. Finally, a moderated mediation model tested the effects of depressive symptoms in such relationships.

RESULT

The emotional components associated with SMAs in reward/loss processing included activations in the left anterior insula (AI) and right dorsolateral prefrontal cortex (DLPFC) during anticipation of working to avoid losses. Activations in both the AI and DLPFC mediated the relationship between DER and SMAs. Moreover, depressive symptoms moderated the relationship between AI activation in response to loss anticipation and SMAs.

CONCLUSION

The current findings suggest that DER link to SMAs through loss-related brain activations implicated in the processing of emotions and motivational avoidance, particularly in youth with greater levels of depressive symptoms. The findings suggest the importance of enhancing emotion-regulation tendencies/abilities in youth and, in particular, their regulatory responses to negative emotional situations in order to guide moderate engagement in SMAs.

Alexithymia and internet gaming disorder in the light of depression: A cross-sectional clinical study

BACKGROUND

Social and emotional deficits are assumed to be involved in the development and maintenance of internet gaming disorder (IGD). Alexithymia refers to a personality construct, which is characterized by deficits in emotional awareness and processing. The constructs of alexithymia and depression share similarities, and depression is a common comorbidity of IGD patients. The aim of this study was to analyze the relationship between alexithymia and IGD when controlling for depression symptom severity. Moreover, we compared alexithymia traits of IGD patients with those of non-pathological video gamers.

METHODS

In a cross-sectional study n = 38 male IGD patients (EG) were recruited at specialized healthcare services in Germany. In addition, n = 39 male non-pathological video gamers (CG) were recruited via social media and bulletin board announcement. Both groups completed questionnaires measuring alexithymia (TAS-20), depression symptom severity (BDI) and IGD severity (s-IAT).

RESULTS

Alexithymia and depression symptom severity both predicted IGD severity. Yet, when including both factors in multiple regression analysis, only alexithymia predicted IGD severity. The prevalence of alexithymia in the EG was 34.2 % (n = 13). None of the non-pathological video gamers scored above the cut-off indicating alexithymia. IGD patients showed higher traits of alexithymia in general and on each subscale, irrespective of whether or not they were currently consuming video games. As previously observed, depression symptom severity was significantly greater in IGD patients compared to healthy video gamers. Yet, group differences in alexithymia traits remained stable, with a ~29 % decrease of effectiveness in the relationship, when controlling for depression symptom severity and sociodemographic factors.

CONCLUSION

The results reveal that alexithymia is associated with and predicts IGD severity independently of depression symptom severity. Moreover, alexithymia is highly prevalent in IGD patients.

The relationship between adolescent emotion dysregulation and problematic technology use: Systematic review of the empirical literature

BACKGROUND AND AIMS

We aimed to systematically identify, evaluate and summarize the research on adolescent emotion dysregulation and problematic technology use. We critically appraise strengths and limitations and provide recommendations for future research.

METHODS

We followed the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) and conducted a systematic review of published original reports on adolescent emotion dysregulation and problematic technology use published until March 1, 2022. A thorough search preceded the selection of studies matching prespecified criteria. Strengths and limitations of selected studies, regarding design and reporting, were identified based on current best practices.

RESULTS

39 studies met inclusion criteria. All of these studies provided on the relationship between adolescent emotion dysregulation and problematic technology use severity based on self-report data.

DISCUSSION

There was a positive correlation between adolescent emotion dysregulation and the severity of problematic technology use. Beyond this, other variables (such as anxiety, depression, self-esteem, etc.) were also closely related to emotion dysregulation and problematic technology use. Such studies are of importance to better understand cause-effect relations regarding both variables.

Quality of Life in Internet Use Disorder Patients With and Without Comorbid Mental Disorders

INTRODUCTION

Evidence from clinical studies on quality of life (QoL) in patients suffering from internet use disorders (IUD) is still limited. Furthermore, the impact of additional mental comorbidities on QoL in IUD patients has rarely been investigated yet.

MATERIALS AND METHODS

In a cross-sectional clinical study 149 male subjects were analyzed for the presence and severity of an IUD as well as other mental disorders by experienced clinicians. The sample consisted of 60 IUD patients with and without comorbid mental disorders, 34 non-IUD patients with other mental disorders, and 55 healthy participants. Standardized clinical interviews (M.I.N.I. 6.0.0) and questionnaires on IUD symptom severity (s-IAT), QoL (WHOQOL-BREF), depression and anxiety symptoms (BDI-II and BAI), and general psychological symptoms (BSI) were used.

RESULTS

Internet use disorder patients showed significantly reduced QoL compared to healthy controls (Cohen's d = 1.64-1.97). Furthermore, IUD patients suffering from comorbid mental disorders showed significantly decreased levels of physical, social, and environmental QoL compared to IUD patients without any comorbidity (p < 0.05-0.001). Multiple linear regression analyses revealed that low levels of psychological, social and environmental QoL were mainly predicted by symptoms of depression. IUD factors were only significant predictors for the social and physical QoL.

DISCUSSION

Internet use disorder patients with comorbid mental disorder reported the lowest QoL. Depression symptom severity was the most significant predictor of low QoL in IUD. Strategies to reduce depressive symptoms should therefore be considered in IUD treatment to increase patients' QoL.

Large-scale network dysfunction in youths with Internet gaming disorder: a meta-analysis of resting-state functional connectivity studies

Internet gaming disorder (IGD) has been defined as a specific behavioral disorder, associated with abnormal interactions among large-scale brain networks. Researchers have sought to identify the network dysfunction in IGD using resting-state functional connectivity (rsFC). However, results across studies have not reached an agreement yet and the mechanism remains unclear. The present research aimed to investigate network dysfunction in IGD through a meta-analysis of rsFC studies. Twenty-two seed-based voxel-wise rsFC studies from 25 publications (594 individuals with IGD and 496 healthy controls) were included. By categorizing seeds into seed-networks based on their location within a prior functional network parcellations, we performed a Multilevel kernel density analysis (MKDA) within each seed-network to identify which brain systems showed abnormal interaction with particular seed-network in individuals with IGD. Compared to healthy control groups, individuals with IGD exhibited significant hypoconnectivity within the default mode network, and enhanced connectivity between the default mode network and insula within the ventral attention network. IGD was also associated with increased connectivity between the ventral attention network and somatomotor regions. Furthermore, the IGD groups showed hyperconnectivity between the limbic network and regions of the frontoparietal network. The results suggest that individuals with IGD show large-scale functional network alteration which underpins their core symptoms including poor emotional competence, cue-reactivity and craving, habitual addictive behaviors and impaired executive control. Whether the compensation mechanism exists in IGD is discussed, and further research is needed. The findings provide a neurocognitive network model of IGD, which may serve as functional biomarkers for IGD and have potentials for development of effective diagnosis and therapeutic interventions.
